SWINGTNGWVINDOW STRUCTURE.

Application fil ed April. 23, 1925. Serial No. 25,254.

Structure, of which the following is a speci fication.

In general my invention relates to that type of window in which the sashboth slides vertically and swings on a horizontal axis relative to thewindow frame.

In this character of window the sash is pivoted on a horizontal axisbetween a pair of vertically disposed sash-bars which are p in turnslidably mounted in the window frame and which are usually provided withthe conventional cords and weights; and my invention particularlyrelates to the mounting of the sash on the sash-bars and the packingbetween thesame which, without interfering with the pivotal movement ofthe window, provides an air-tight joint when the sash is vertical andalso prevents rattling.

In the accompanying drawings wherein I lllustrate the application of myinvention,

Fig. 1 is an inside elevation of:a window.

frame provided with an upper and lower sash, the upper sash being shownin its closed or vertical position while the lower sash is swung on ahorizontal ariis into a tilted position; Fig. 2 is an enlarged brokenvertical section of a sash taken along the line II- H in Fig. 3; Fig. 3is a=broken horizontal section on enlarged scale and taken along theline IIIIII in Fig. 2, and Fig. 1 is' a broken section on the line IV-IVin Fig. 3.

The following is a detailed description of the drawings. 1

A 's the window frame which isshown of the conventional type provided atits vertical sides with grooves to receive the edges of the upper andlower sash. The upper sash is indicated at Band the lower sash at BPreferably both the upper and lower sash are constructed in accordancewith my invention, but if desired one of them may be of the ordinaryvertical sliding type. The sash are each mounted on a horizontal axisbetween pairs of sash-bars C which are mounted to slide in the usualsash-grooves in the window frame A. The bars C are n'eferably providedwith the usual cords and weights.

The edges of the sash and the sash-bar are in flat surface contact whenthe sash is vertical as shown in Fig. At their centers the sash-bars Gare pierced by horizontal circular holes whose outer portions are ofgreater diameter, thus providing an intermediate shoulder 1. The innerand smaller diameter of the hole is provided with a bushing 2 whoseouter end has a foot flange 3 which is countersunk into the outersurface of the sash bar and attached in place by screws 4. 5 is ahollow. stud of proper which is countersunk in the edge of the sash andsecured by screws 7 to said sash. The bore of the stud 5 is threaded toreceive a screw 8 which extends through a washer 9 bearing against theend of the outer bushing 2. Thus the sash is pivoted on a horizontalaxis between and to the bars C, the two flanges 3 and 6 forming ametallic hearing which assumes thewear from the wooden elements.

Each vertical edge of the sash is provided with a vertical slot 10 inwhich is mounted the metal channel member 11, the same being held inplace by its rearwardly extending horizontal tongues 12 seated inrecesses 13 in the upper and lower ends of the sash and held in place byscrews 14.

15 is a metal packing bar having its front edge rounded and which is ofproper widtl'i to fit in the channel 11. 16 represents screw boltsextending loosely through holes in the rear wall of the channel member11 and having their front ends screwed into threaded holes in the bar15. Helical springsl? are coiled about said bolts between the rear wallof the channel and the bar, thus resiliently forcing the bar outwardly.The heads of the screw-bolts prevent the dislodgment of the bar from thechannel when the sash is swungfrom the vertical. The sash is providedwith sockets 18 in the rear of the channel member to provide clearancefor the inner ends and heads of the screw-bolts. Said bolts and springsare provided at proper intervals to properly support the packing bar inposition.

Each of the sash-bars is provided with a trough shaped slot 19 whichregisters with the slot in the sash when the latter is vertical. Theslot 19 is provided with a metal trough member 20'which is held in placeon the bar by its end tongues 21 seated in recesses in the ends of thebar and attached by screws 22. The trough members 20 are of a flattenedare cross-sectional shape with which the rounded edges of the bars 15mate and into and out of engagement with which said bars may readilymove as the window is swung on its axis.

It is evident that when the sash is in its vertical position the packingbars are forced in a resilient mating with the troughs and that anair-tight and rattle-proof joint is effected. It is further evident thatwhen the window is swung out of the vertical the bars being springmounted are readily disenaged from the troughs by the applicatlon of aslight force. It is also evident that when the window is swung backintothe ver-' tical thepacking bars will snap into mating engagementwith the troughs.

hat I desire to claim is:-

1. In a sliding and swinging window structure the combination with awindow frame, of a pair of sash-bars mounted to slide vertically in saidframe and a window sash interposed between said bars, of a horizontallydisposed journal member sunk into each of said sash-bars, a horizontallydisposed stud extending from each vertical edge of said sash andjournaled in the corresponding journal member, said studs havingthreadedbores, washers bearing against theends of said journal members andstuds, and screws extending through said washers V and screwed into thethreaded bores of said studs. v I

2. In a sliding and swinging window structure, the combination with awindow frame,zof a pair of sash-bars mounted to slide vertically in saidframe and a window sash interposed between said bars, of a horizontallydisposed bushing sunk into each of said sash-bars, a horizontallydisposed stud extending from each vertical edge of'said sash andjournaled in the corresponding bushing, said studs having threadedbores, washers bearing againstthe ends of said bushings and studs, andscrews extending through said washers and screwed into the threadedbores of said studs.

3. Inya sliding and swinging window structure, the combination with awindow frame, of a pair of sash-bars mounted to slide vertically in saidframe and a window sash interposed between said bars, of a h0rizontallydisposed bushing sunk into each of said sash-bars and provided with afoot flange substantially flush with the surface of the bar, ahorizontally disposed stud extending from each vertical edge of the sashand journaled in the corresponding bushing, said -stud having a footflange in flat contact with the foot flange of the bushing, said studsbeing provided with threaded bores, washers bearing against the ends ofsaid bushings and studs, and screws extending through said washers-andscrewed into the threaded bores of said studs.

.4. In a sliding and swinging window structure, the combination with awindow frame, of a pair of bars mounted to slide vertically therein andeach having a vertical slot on its inner face, means whereby a sash ispivotally mounted between said bars'to swing'on ahorizontal axis, saidsash interposed between said sash-bars and provided with vertical sidegrooves, a metal channel member mounted in each of said grooves, apacking-bar having'its outer end contoured to fit the slot on thesash-bar, members fixed to said packing-bar and extending throughtherear wall of said metal channel, helical springs coiled about saidmembers and tending to press said packing-bar outwardly, the inner endsof said members being provided with heads to prevent their disengagementfrom said channels.

5. In asliding and swinging window struc-- ture, the combination with awindow frame, of a pair of bars mounted to slide vertically therein andeach having a vertical slot won its inner face, means whereby a sash ispivotally mounted between said bars to swing on a horizontal axis, saidsash interposed be tween said sash-bars and provided with ver- -ticalside grooves, a metal channel member mounted in each of said grooves, apacking-bar having its outer end contoured to fit the slot on thesash-bar, bolts having their threadedends fixed to the packing-bar andextending rearwardly throughthe rear wall of the channel, and helicalsprings coiled about said bolts between the packing bar and the rearwall of the channel whereby said packing-bar is resiliently pressedoutwardly, the heads of said bolts by engaging the rear of said channelpreventing the dislodgment of the packing-bar from its channel.
